It is stated that if you are able to overcome others, you are strong. If you can overcome yourself, you are stronger. Every day people most likely live in the competitive battles such as education, career, social position and politics. That’s why people work against one another. However, to win others is not great because it can be defeated later. But to win oneself is the greatest, ever. Therefore, there is a saying: to win a hundred wars is not greater than to win oneself.
